Acupuncture has had a long and interesting history. However acupuncture still faces challenge from its mechanism explanation. The traditional acupuncture theory may not fully explain electroacupuncture. This study carries out an investigation into electroacupuncture from bioenergy, bioelectricity, and electrotherapy points of view. An experimental and theoretical study of the electrical property of acupoints is conducted. An equivalent model of tissues under electroacupuncture electrical field is developed. In conjunction with this, an improved technique is used in the resistance test to investigate the electrical properties of acupoints, in which the "least-value hunting" method, forcecontrollable probe, and square electrical waveform have been adopted. The currently used apparatus for electroacupuncture is improved by the development of computer-based electroacupuncture instrumentation. On the basis of this development, the methodology of Internet-based remote control and monitoring is introduced in the therapeutic and training process. A standardised and quantified elctroacupuncture is investigated through the implementation of a fuzzy decision making system. The fuzzy controllers are developed and embedded in a PC-based instrumentation system to overcome "accommodation", which occurs during the electroacupuncture process.
